摘要： The positions of brush seal segments are positively adjusted relative to a housing carrying the brush seal segments and the opposing sealing component by employing members formed of thermally responsive material. The members are heated by heating elements receiving controlled power. By increasing or decreasing the power provided to the heating elements, the members are expanded or contracted to move the brush seal segments toward or away from the opposing sealing component.

摘要： A brush seal segment is mounted within a pressure vessel and against an arcuate surface of an element to provide a seal between regions on opposite sides of the seal at different pressures. By vibrating the vessel through a range of frequencies, natural frequencies of the brush seal under pressure loading can be ascertained. Additionally, by adjusting interference between the arcuate surface and the bristle tips, natural frequencies of the brush seal under various interference loadings can likewise be ascertained. The pressure vessel has mounts for attaching the vessel to a shaker table to facilitate vibrating the vessel through the range of frequencies.
摘要翻译：刷密封段安装在压力容器内并抵靠元件的弧形表面，以在不同压力下在密封件的相对侧上的区域之间提供密封。通过在一定范围的频率振动容器，可以确定在加压负载下刷子密封件的固有频率。此外，通过调整弧形表面和刷毛尖端之间的干涉，同样可以确定各种干涉负荷下的刷密封件的固有频率。压力容器具有用于将容器附接到振动器台的安装件，以便于在该频率范围内使容器振动。

摘要： A rotary machine includes a rotatable rotor, blades radially mounted on and spaced apart about the rotor, a stationary casing disposed about and radially outward from the rotor and blades defining an annular gap between the casing and tips of the blades, and a flexible abradable seal assembly attached on the casing and disposed within the annular gap such that during differential growth of the rotor and blades relative to the casing the seal assembly flexes and abrades in response to contact by the blade tips and thereby clearance between the casing and blade tips is controlled as to avoid contact by the moving blade tips with the casing.

摘要： A brush seal is provided between a first stationary component and a second rotating component. A cooling medium is provided through a plurality of jet nozzles for flow along an upstream surface portion of the brush seal bristles and along the rotating component surface adjoining the tips of the bristles. The cooling medium cools the brush seal bristles to a temperature below the temperature of the working fluid passing through the turbine. The jet nozzles may be arranged in the shroud or in the upstream backing plate of the brush seal to direct the cooling medium toward the juncture of the brush seal and the sealing surface.

摘要： In a hydrogen cooled generator, a seal casing has a chamber opening radially inwardly for receiving a pair of seal rings forming a fluid film along the interface between the rings and the rotor. A spring biases the seal rings against axial spaced flanges of the seal casing and static oil sealing grooves are provided at the interface of the seal rings and flanges. A brush seal is carried by one or both of the seal rings or by the seal casing and has bristles for engaging the surface of the rotor. The combination of seal rings and brush seal form a low flow fluid film seal maintaining the hydrogen atmosphere and oil on opposite sides of the housing wall and the seal casing segregated from one another.

摘要： A seal is provided around a shaft extending through a cavity in a hydrogen cooled generator. The seal includes a plurality of brush seal structures adapted to reduce flow to/from the cavity to a level where the risk of creating an explosive mixture of gases is minimized. In an embodiment of the invention, a series of brush seals are provided to interface with the rotary shaft so as to define a seal for minimizing the flow of hydrogen out of the cavity. In one preferred embodiment, the seal is composed of first and second brush seal assemblies, each of which is comprised of a plurality of brush seal structures. In another embodiment, spring(s) are provided to urge the brush seal structures into sealing engagement with the rotor. If deemed necessary or desirable, a vent outlet is provided in a cavity wall remote from the hydrogen atmosphere, to remove hydrogen that has leaked through the brush seals.
